This present study compares the characteristics of biochars produced by slow pyrolysis at 400-450°C for the biological substrates namely, Coccus nucifera shells (CNS) and Prosopis glandulosa hard wood (PGH). Biochar yield of the biomass substrates varied from 25-28 %. C/N ratio and Cation Exchange Capacity (CEC) was found to be higher in PGH biochar as 11.25 and 16.70 cmolkg-1 respectively. Thermo gravimetric analysis (TGA) of CNS derived biochar showed maximum yield of biochar of about 83.75 % when compared to PGH biochar. It was inferred that before and after biochar production the materials were differed much in their physical, chemical, nutrient, thermal and biological characteristics, particularly total carbon content varied from 49 to 61%. From this study, the carbon sequestration potential of the biochar was calculated as 2635 tonnes of CO2 reduction per year.
